3 Sheets-Sheet 3 pin openings as indicated at 24 in Fig. 1 and clamping

bolts

25 and 26 are provided edgewise through the bifurcated ends of the flanges whereby the portions of the pin extending through the flanges may be securely clamped in position.

The enlarged cylindrical end portion 28 of the pin is is flattened on one side as indicated at 29 providing clearance for the bolt 25 therepast. The bolt 25 engaging with the flattened portion is of the pin thus prevents rotational movement of the pin l9 but upon loosening of the

clamping bolts

25, 26 longitudinal adjustment of the pin i9 is permitted.

An annular, or cylindrical, member 3| extendlng concentrically with and in a spaced relation about the pin la is provided with an integral extension 32 which is adapted to be rigidly secured such as by welding to the end of one arm 33 of the draft tongue. Arranged between the cylindrical member 3| and the pin I9 is a relatively thick walled bushing 34 of resilient compressible material, such as rubber or its equivalent, the outer surface of which bushing is of cylindrical shape having a diameter corresponding substantially to the inner diameter of the cylindrical member 3|. The bore through the bushing 34 is tapered throughout the greater part of its length with the angle of taper corresponding generally to the angle of taper of the pin 20.

In the assembly of the mounting the cylindrical member 3| with the bushing 34 inserted therein is first positioned between the flanges H and l2 and with the clamping bolt 25 removed the pin i5 is then inserted longitudinally through the flange ll. The bore within the bushing 34 is of such diameter that the end of the pin 2| initially barely extends past the outer surface of the flange l2 so that the nut 22 may be threaded firmly thereupon, The bolt 25 is then inserted loosely in place to prevent rotation of the pin l9 and the pin is then drawn tight by the nut 22. By virtue of the central tapered portion 20 of the pin l9, as the nut 22 is tightened the bushing 34 is expanded so as tightly to compress it against the inner surface of the surrounding cylindrical member 3|. In order to minimize extrusion of the bushing materia1 past the opposite ends of the cylindrical member 3|

annular ribs

36 and 31 are provided upon the inner surfaces of the flanges ii and i2, respectively, concentrically about the pin openin The bushing 34 may be thus readily compressed to such a degree as may be necessary to hold the tongue arms 33 in a predetermined horizontal position even though the outer end thereof may be unsupported for facilitating the coupling of the outer end thereof to the rear end of a truck vehicle. While the tongue may thus be firmly supported against hinging movement due to its own weight the bushing material is nonetheless sufficiently resilient to permit such hinging movement as may be necessary during normal running conditions when the rear end of the truck and the forward end of the trailer will experience certain vertical movements relative to each other.

In usage over prolonged periods of time the bushing 34 may become worn or otherwise deteriorated to the point that its replacement is necessary and which replacement may readily be effected simply by removing bolt 25, loosening bolt 25, removing nut 22 and driving the pin l9 endwise from the assembly. Due to the taper on both the pin l9 and of the bore of the bushing 34 the pin I!) may readily be freed of the bushing. The cylindrical member 3| may then be removed from between the flanges II and I2 and since the outward pressure exerted against the inner surface of the bushing is relieved the bushing 34 may easily be removed from the cylindrical member for the insertion of a new bushing.

In the modification of the invention illustrated in Fig. 3 the supporting block member 40 is substantially similar to the supporting block ID as previously described. The cylindrical member 4| for rigid attachment to the end of the tongue arm is also similar to the corresponding member 3| as previously described except that it is somewhat shorter for reasons as will be more fully described hereinafter. The pin 42 is somewhat similar to the pin l9 as previously described except that the large cylindrical end 43 has a diameter somewhat greater than the end of the adjacent tapered surface so that a right angular shoulder 44 is provided therebetween and facing toward the opposite end of the pin 42. An annular ring 45 is provided about the pin 42 and engages with the shoulder 44 so that it is axially movable with the pin 42 upon adjustment of the nut 46 and engages with the adjacent end of the bushing member 41, Upon tightening of the nut 46 and upon resultant longitudinal movement of the pin 42 the bushing 4'! is expanded and compressed against the inner surface of the cylindrical member 4| in the same manner as described in connection with the modification shown in Figs. 1 and 2. Further, the annular ring 45 engaging with the adjacent end of the bushing 41 exerts a compressive force upon the bushing in a longitudinal direction of the pin 42 simultaneously with the radial compression. The surface of the ring 45 next adjacent the bushing 41 is provided with a concentric annular rib for minimizing the extrusion of the bushing material through the gap between the ring and the adjacent end of the cylindrical member 4|.

The modification shown in Fig, 4 combines certain of the features of the two preceding modifications. In this instance the supporting block 55 and the cylindrical member 5| attached to the end of the'tongue arm are similar to the corresponding elements of the preceding modification while the pin 52 in this case is similar to the pin l9 of the first modification except that it is provided with an enlarged head '53 integral with the large end thereof. An annular ring 54 is provided about the small diameter cylindrical end portion 55 of the pin between the inner surface of the adjacent flange of the supporting block 50 and which is adapted to engage with the adjacent end of the rubber bushing member 55. The opening in the flange of the supporting block about the small diameter end of the pin 52 is enlarged for cooperatively receiving a longitudinally split sleeve 58 which is of a length greater than the thickness of the flange and extends between the ring 54 and the nut 59 threaded onto the end 50 of the pin.

In the assembly of this structure, as the pin 52 is first inserted in position the enlarged head 53 will be spaced somewhat outwardly from the outer surface of the adjacent flange of the supporting block 55 as indicated by dotted lines. As the nut 59 is then tightened pressure will be exerted against the ring 54 and the adjacent end of the bushing member 56 and the pin 52 will first be drawn longitudinally through the bushing so as to expand the bushing and compress it radially between the tapered mid-section of the pin and the inner surface of the cylindrical member 5|. Upon continued tightening of l t e ut h hl r e hea lult ma y be drawn into contacting engagement with the adjacent surface of the supporting block flange whereupon further longitudinal movement of the pinwill'b'e precluded while compression of the bushing 56 in "the axial direction thereof will be efiected by movement of the ring 54 axially thereagainst.

'As'mentioned, the sleeve 58 about the cylindrical end portion 55 of pin 51 is longitudinally split so. as to be compressible upon tightening of the clamping bolt 61 extending edgewise through the correspondingfiange of the support--v ing block. Thus following an adjustment of the pin 52 it"may be firmly secured in place by the clamping. bolts through both flanges of the bear! ing block and thus relieving the nut 59. of continous load thrust. t

In the modifications of Figs. 3 and 4. tightening of the tongue mounting is accomplished by endwisecompression of the rubber bushing upon a tapered pin. It will be obvious to those skilled in the art that it is not essential to the present invention that the taper be provided, upon the pin since the same Wedging action of the bushing may be accomplished equally well by pro-, viding the tapering surface on the inner wall of the outer annular member. In such case the pin may be cylindrical throughout its length and having a collar thereabout engaging one end of the bushing for effecting endwise compression thereof.

This variation is embodied in the modification illustrated in Fig. 5 which discloses a supporting block member 65 substantially similar to the block members as previously described but having

opposite side walls

56 and 51 drilled for receiving a cylindrical pin 58 therethrough. Surrounding the pin Elsie a double frusto-conically tapered. annular member 09 which is provided with an integral extension 10 for attachment thereto of a tongue arm. Arranged about the pin 68 within the annular member tie-are a pair of frusto-conically shaped bushings II and I2 which are of such a length that a relatively wide gap 'I3 is provided between the inner ends to allow for movement of the bushings toward each other. The pin 08 is provided with a head 14 at one end and is threaded at the other end having a nut I5 arranged thereupon. Arranged about the pin Gil-adjacent the threaded end is a compression collar I5 which is adapted-to be engaged by the end of a split sleeve ll extending through the flange 6 cf-the supporting block. By tightenin of'the nut 75 force is transmitted through the sleeve 7'! against the collar 16-which will exert an endwise ings TI and I2 so as to wedge them between the relatively tapered surfaces of the pin 58 and the surrounding annular member 69 whereby the necessary degree of tightness of the mounting may be effected. The ends of'the

flanges

65 and 67 of the supporting block B5 are split as in the previous instances and bolts 18 and 19 are provided therethrough in order that the opposite ends of the pin 68 may be firmly clamped in place not only to prevent rotational movement of the pin 68 butalso to relieve the head M and the nut 15.

The modification shown in Fig. 6 is a still further embodiment of the present invention similar in some respects to the modification of Fig. 5 except that instead of providing a double taper upon the annular member surrounding the pin, the pin itself is provided with a double taper. The structure of this modification. includes supportingv block member. 85; having,oppositaside.
